4. Machinability: The increased beam strength, reduced ductility, clean surface and improved dimensional accuracy of a cold drawn bar can positively affect machining performance by:
- Allowing the use of rapidly activated, precision colleting
- Increase work-holding security with larger bearing contact areas
- Improve the machined surface finish through reduced tool-edge weldments on ductile grades
- Improve part size control through less lateral deflection
- Increase tool life through more stable tool-edge weldments on ductile grades as well as from reduced abrasion with oxide-free, bar surfaces
- Reduce wear on machine parts and collets and less lubricant contamination due to the absence of hot mill surface scale and/or corrosion products
- Allow the use of higher spindle speeds with the reduced propensity for vibration
- Reduce screw machine maintenance
5. Complex Shapes & Sections: Complex shapes and sections can be produced at a lower cost and lesser investment. Ability to produce shapes with tighter tolerances facilitates lower production costs, need for lesser equipment, machinery & manpower and reduces the scrap generation.
Summary
In summary, cold finished steel bars enable design engineers to reduce manufacturing costs and time, and produce superior performance components. Cold finished steel bars are the value-added engineering material of choice for a universe of precision components in almost every industry.
